Functional Diagram
General Description
The HMC588LC4B is a wideband GaAs InGaP HBT
MMIC Voltage Controlled Oscillator which incor-
porates the resonator, negative resistance device,
and varactor diode. Output power and phase noise
performance are excellent over temperature due to
the oscillator’s monolithic construction. The Vtune
port accepts an analog tuning voltage from 0 to +13V.
The HMC588LC4B VCO operates from a single +5V
supply, consumes only 55 mA of current, and is housed
in a RoHS compliant SMT package. This wideband
VCO uniquely combines the attributes of ultra small
size, low phase noise, low power consumption, and
wide tuning range.

List of Materials for Evaluation PCB 108648 [1]
The circuit board used in the application should
use RF circuit design techniques. Signal lines
should have 50 Ohm impedance while the package
ground leads and exposed ground paddle should
be connected directly to the ground plane similar
to that shown. A sufficient number of via holes
should be used to connect the top and bottom
ground planes. The evaluation circuit board shown
is available from Hittite upon request.
